CROWN CT 875 - Eight-channel power amplifier, 75W @ 4Ω

CROWN CT 875 – Eight-channel power amplifier, 75 W @ 4 Ω

The CROWN CT 875 is an eight-channel installation amplifier delivering 75W per channel into 4Ω (also 75W @ 8Ω) in a fanless 1U chassis. Based on DriveCore™ technology, it integrates the drive stage and power stage into a single, highly efficient circuit (>90%), while maintaining the sonic quality of an evolved Class AB design. Its universal power supply and passive cooling make it ideal for conference rooms, retail, restaurants and corporate environments, while its built-in life safety features and XFMR 4/8 compatibility allow use in 70V and 100V applications.

Main features

• Channels: 8 independent, 75 W @ 4 Ω / 75 W @ 8 Ω
• Input sensitivity: 1.4 V for rated power
• Signal-to-noise ratio: 110 dB (A-weighted)
• THD: < 0.05% at rated power
• Frequency response: ± 0.5 dB (20 Hz–20 kHz)
• Crosstalk: > 70 dB (20 Hz–1 kHz)
• Common mode rejection: > 55 dB (20 Hz–1 kHz), typically > 70 dB
• Voltage gain: 25 dB
• Input routing: multiple, with balanced barrier block or Phoenix
• Cooling: natural convection, no fans
• Power supply: universal 100–240 VAC, 50/60 Hz
• Human security: integrated life-safety functions
• DriveCore™ Efficiency: > 90%
• Protections: Patented feedback and limiting circuits
• Load stability: 2 Ω–16 Ω; requires XFMR 4/8 for 70 V/100 V

Product benefits

• Simplified installation: single rack space, minimal cabling, and no noisy fans.
• Energy efficiency: low consumption and minimal heat dissipation thanks to DriveCore™.
• Continuous reliability: passive design and high-durability components for 24/7 use.
• Professional sound quality: low distortion, high S/N and flat response throughout the range.
• Flexibility: Easily adapts to low impedance or constant voltage systems.

Use cases

• Sound systems distributed in shopping centers and airports.
• Public address and emergency evacuation installations.
• Background audio in hotels, restaurants and corporate spaces.
